Dagger Lane Pond, 1949 A similar picture to that of 1948, but metamorphosis was earUer. The contrast in size between the "West" and the "SaUow" tadpoles on 19th June should be noted. These two sites were only about 2 m apart. Ponds were generally full. The season opened with exceptionally hot weather and, apart from some rain in May, it was very hot and dry throughout. Except for the winter, therefore, the season resembled 1947 rather than 1948. The appearance of the pond and its vegetation also resembled that of 1947. The patches of starwort were there—in fact large areas of the pond were completely covered—the rushes had.
